abits. Araneides wandering after prey, making no web,

rks: This differs in many points from Myrecta, 
Latr., Ann. des Sc. Nat. IV. p. 261, and yet seems to be 
closely related to it. That subdivision is not known to me, 
though it is said in that work that some species are found in . 
Georgia. In Myrmecta the cheliceres are large, in this, they 
are small, at least in the females ; in that subgenus the maxil-

the cephalothorax, and they have other characters which do 
not belong to this. HPV 
I have already pointed out the features, and proposed a 
name for this singular subdivision, in a paper published in 
Silliman’s Journal. I have, since writing that article, discov- 
ered one species, in addition to the three mentioned there. 
They are all anomalous, and differ from each other in many
